The Development of Double-Oriented Silicon Steel with Cube Orientation

Silicon steels with cube orientation were extensively studied in the 1950s and 1960s, primarily for the purpose of using them as core materials for generators and large motors. In this paper, the research and development history of double-oriented silicon steel is outlined, as are the original attempts to subject hot bands containing AlN precipitates to cross-rolling treatment. It was found that the hot bands developed a (001) plane oriented secondary recrystallization structure after cross rolling and annealing, and that the percentage of grains with either (001)[100] or (001)[110]-orientations varied in accordance with the contents of carbon and AlN contained in hot band. Finally, some related fundamental research is discussed.
